PublicationRecent advancements in ergonomic risk assessment integration of artificial intelligence, wearable technology, and industry-specific approachesErgonomic risk assessment is crucial in preventing work-related musculoskeletal disorders (WMSDs) across various industries. Traditional methods, while effective, have limitations, such as reliance on manual observations and a lack of real-time monitoring. Recent technological advancements, including artificial intelligence (AI), wearable sensors, and industry-specific solutions, are addressing these gaps. AI and machine learning techniques enable real-time data analysis, providing more accurate and proactive ergonomic assessments. Wearable technology, such as inertial measurement units and pressure sensors, offers continuous monitoring of worker movements and postures, helping to prevent injuries in sectors like healthcare, construction, and manufacturing. These tools also allow for personalized ergonomic interventions by assessing individual risk factors in real-time. Industry-specific approaches have also emerged, particularly in high-risk fields such as healthcare and mining, where the integration of ergonomic and psychosocial stressors provides a comprehensive risk assessment model. In addition to physical ergonomics, advancements now incorporate psychosocial factors, addressing issues like organizational culture and job stress, which significantly influence musculoskeletal health. Finally, technological innovations such as simulation and modeling tools further enhance ergonomic assessments by simulating worker movements and identifying high-risk postures. However, challenges remain in standardizing these tools and integrating them into existing workflows. The evolution of ergonomic risk assessments towards more automated, precise, and real-time systems promises to reduce WMSDs and improve overall workplace safety.

PublicationCurrent trends and risk factors in low back pain: an ergonomic perspective on prevention and managementLow back pain (LBP) is a global health concern, impacting individuals across various professions and age groups. This review explores the critical role of ergonomic factors in the prevention and management of LBP. Occupational risk factors, including heavy lifting, prolonged sitting, non-neutral postures, and repetitive motions, contribute significantly to the rising prevalence of LBP. Professions such as healthcare, law enforcement, and office work are particularly vulnerable due to their physical demands and static postures. Ergonomic interventions, including task redesign, assistive technologies, and workplace modifications, have proven effective in reducing the incidence of LBP. Dynamic seating, lumbar support devices, and wearable technology are among the innovations that have been introduced to promote healthier postures and reduce musculoskeletal strain. Additionally, ergonomic training programs focusing on proper body mechanics and posture correction are essential for long-term prevention. Beyond physical factors, psychosocial and lifestyle elements, such as stress, sedentary behavior, and smoking, also play a role in the development of LBP. Combining ergonomic interventions with health-promoting behaviors, such as regular physical activity and stress management, can significantly reduce the burden of LBP. Technological advancements, including mobile applications and wearable devices, support adherence to home exercise programs, offering continuous feedback for posture correction and movement. This comprehensive review underscores the need for a multidisciplinary approach that integrates ergonomic interventions, technological tools, and lifestyle modifications to manage and prevent LBP effectively in both occupational and everyday settings.
